More information - my weed razr arrived today, after assembling I took it down to the pond to start cutting and raking. My homemade cutter had been bringing up what I thought was only CLPW and FA. I knew it was just gliding over the tops of most of the weeds, hence the new cutter. I have now found out that the bulk of my weeds is not CLPW but Southern Naiad or Bushy Pondweed. When I find my camera I will post some pics, pretty sure that's what it is - looks very similar to Sago pondweed and Widgeon Grass, but pretty sure it is the SN. Not sure how this changes anything, it isn't a foreign invasive but it sure has taken over the pond along with the CLPW. Also still pulling up CLPW and FA but I'd say the bulk of the weeds are the new culprit.
